Hi Ignacio,
The sgagility project has been tremendous help for me in trying to get a grip
of how things work. I find it a bit hard to understand all the flexibility that
lies within hobo, and sgagility sort of opened up a few doors so to say. I
first started using rails when I found Hobo and was pretty fresh at Ruby as
well, so there has been a few things to sort out, but it is coming together now.
To the point:
What I wanted was to have a project that is merely a description of what kind
of data the project represents, and then files should be attached to this
project as a set belonging to a projectfile. In other words: The projectfile
should be a container that keeps track of which uploads that belong to a
certain project.
I understood from your comments (thanks) that I missed an abstraction layer,
and changed the relationships as follows:
Project has has many projectfiles and projectfiles has many uploads.
The idea behind this is that any project can be created and assigned to any set
of projectfiles, and then the project needs to own the projectfile container
which again owns the uploads.
The uploads are created from the projectfile edit-page (since it is required to
create a projectfile before uploading).
It is all working now, and the controller for projectfiles looks like this, and
I'd be glad to get feedback on it if it should be done in another way:
class ProjectfilesController < ApplicationController
hobo_model_controller
auto_actions :all
def index
hobo_index do
@projectfile = Projectfile.new
end
end
def show
hobo_show do
if params[:style]
send_file @projectfile.prattach.path(params[:style])
else
render
end
end
end
def update
hobo_update do
Upload.create(
:file_name =>this.prattach_file_name,
:file_type =>this.prattach_content_type,
:file_size =>this.prattach_file_size,
:file_created =>this.prattach_updated_at,
:projectfile_id => this.id
)
respond_to do |format|
format.js { hobo_ajax_response }
format.html { redirect_to @projectfile }
end
end
end
end
Best,
Arve
